10 Claims.

This invention relates to gas lighters for wick oil burners and moreparticularly to such a lighter in which the opening of a gas valveserves automatically to light the wicks of one or aplurality of oilburners. Wick oil burners are in extensive use, particularly in cookingranges, and the manual lighting of these burners is an inconvenient andburdensome task. The primary object of my invention is to provide anovel gas burning mechanism for conveniently lighting such burners.

Range oil burners of the wick type are commonly of annular configurationand each wick has cooperating therewith annular perforated ;cylindersproviding a combustion chamber therebetween, each burner usuallyemploying two annular and relatively concentric wicks and a pair ofperforated cylinders cooperating with each wick. In accordance with myinvention, I pro- ,vide means for conducting wick-lighting gas to thewick chamber and/or to a chamber located between two adjacent wicks, andcooperating therewith I provide a pilot jet. The pilot jet normallyremains lighted with a small flame. Gas is conducted from a commonsource to the wick chamber and jet and this gas is under the control ofa single manually operated valve. The pilot jet is provided withapertures arranged to project a flame or flames to a position ignitingthe wick-lighting gas and such flames are projected only when the valveis opened. Opening movement of the valve causes a flow of wicklightinggas and increases the flow of gas to the jet whereupon the projectedflames light the wick-lighting gas which thereupon serves to light thewick. The invention may be constructed in diiferent forms and in oneform illustrated in the drawings the valve serves automatically topermit an advance flow of gas to the wick chamber as and for thepurposes hereinafter described. The production of an improvedwick-lighting apparatus of this nature comprises a further object of theinvention.

These and other features of the invention will be best understood andappreciated from the following description of preferred embodimentsthereof selected for purposes of illustration and shown in theaccompanying drawings, in which Fig. 1 is a fragmentary side elevationof two wick oil burners having my improved gas lighter applied thereto,

Referring first to the form of my invention illustrated in Figs. 1-4,two oil burners are indicated at l0. Each burner embodies two annularand concentric channel members l2 having wicks l4 therein. Mounted onthe channel members at opposite sides of and extending upwardly from thewicks are concentric cylinders l6 perforated at H. Oil is fed to thechannel members in the usual and well-known manner (not illustrated).

A gas supply pipe l8 has communication with two pipes 22 and 22 througha valve member 24. The pipe 20 branches at 26 into two pipes 28respectively for the two burners. Each such pipe 28 extends upwardlybetween the two channel members l2 and the two inner cylinders I6 andcarries an inverted U-shaped gas deflecting shield 29 on top and betweenlock nuts 30, the shield having contact with the two adjacent cylinders.The top end of each pipe 28 is closed .and gas exit ports 32 areprovided therein beneath the shield and substantially in alignment withperforations I! in the cylinders opposite to the wicks.

The pipe 22 extends to a point beneath the burners Ill and is providedwitha pilot jet 34 on its top end, the jet having gas exit portsdirected upwardly toward the pipes 28 within the burner openings. Aby-pass 36 in the valve member permits a continuous flow of gas to thejet, this flow being regulated by a screw 38. The pipes 20 and 22 are incommunication with ports 40 and 42 in the valve member 24, and screws 4!and 43 are provided for adjustably limiting the flow of gas throughthese ports. Within the valve member 24 is a valve 44 adapted to berotated by a handle 46. Gas from the supply pipe it enters a port 48 inthe valve and is adapted to pass therefrom through ports 50 and 52 tothe pipes 20 and 22 when the valve is rotated clockwise (Fig. 3), theport 50 preferably being provided with an extension 54 for providingcommunication with the port 40 in advance of communication of the port52 with the port 42.

It will now be apparent that the by-pass 36 keeps the pilotlightcontinuously lighted. When it is desired to light one of the burnerwicks, the oil 55,

valve to the burner or burners having been opened for a sufficient timeto saturate the wicks, the operator merely rotates the valve handle 46clockwise. Communication of ports 54 and 58 with port 41 thereuponcauses a flow of gas through the pipe 29 to the chambers within theshields 29 and this gas flows outwardly through exit ports 32 andperforations I! to the wick chamber. Communication of port 52 with port42 increases the flow of gas to the pilot jet whereupon the pilot flames56 are projected into the burner openings as illustrated in Fig. 1. Thegas within the shields 29 is thereupon ignited and the gas and flamespassing through the perforations into the wick chamber in turn lightsthe wicks. It should be particularly noted that the port 54 serves toprovide a supply of gas in the wick and shield chambers in advance ofprojecting the flames 56, it being understood that the valve 44 isopened only momentarily to efiect the lighting of the wicks. Thisadvance flow of gas is of importance since the gas flame will notreadily flash through the cylinder perforations to the wick chambersunless gas is already present in the wick chambers.

In Figs. and 6 is illustrated a somewhat modifled form of the invention.The burners are the same as illustrated in Fig. 1 and the flow of gasthrough pipes 6G and 62 is controlled by a valve 64 in like manner as inFig. 1 except that this valve has no port corresponding to the extendedport 54. The pipe 60 has two branches $56 each provided with a T-shapednozzle 61 on its top and extending through the adjacent cylinders andinto the wick chambers. Each nozzle tip has two gas exits, one directedtoward the wick and the other directed upwardly. The pilot pipe 62extends to a position above the top ends of the cylinders and isprovided with jet openings directed over the top ends of the cylinders.When the valve 64 is opened, gas flows into the wick chambers andupwardly within the cylinders. Simultaneously therewith the flow of gasthrough the pipe Bil is increased to project the flames 68 over the topsof the cylinders. These projected flames ignite the gas within thecylinders whereby the gas at the nozzles 6'! is ignited and in turnlights the wicks.

The form of the invention illustrated in Fig. '7 is the same as in Fig.5 except that shields 10, like the shields 29 are employed in lieu ofthe nozzles 61.

It will now be apparent that I have provided a relatively simple andefficient gas lighter for wick oil burners and furthermore that theconstruction is such as readily to adapt the apparatus to oil burnersnow in use.
